MANUFACTURE OF COIN-CASES.

SPECIFICATION forming part of Letters Patent No. 559,263, dated April 28, 1896.

Application filed August 4, 1 8 9 2.

To all whom, it may concern.-

Be itknown that I, ROBERT L. CHOP'E, acitizen of the United States, residing at Detroit, in the county of lVayne and State of Michigan, have invented certain new and useful Improvements in Machines for Manufacturing Ooin-Gases, of which the followingis a specification, reference being had therein to the a top plan view of my machine. Fig. 2 is a side elevation, partly in section. Fig. 3 is a cross-section on line y 1 Fig. 2. Fig. tis an enlarged section of the forward end of the ma chine, showing the dies, &c. Fig. 5 is a similar section of the dies, showing the parts in a different position. Fig. 6 is a cross-section through the dies at right angles to the section in Fig. 4. Fig. 7 is a similar section showing the parts in a different position. Figs. 8, 9, and 10 are plans showing the manner of folding the paper to form the blank. Fig. 11 is an end elevation of Fig. 10. Fig. 12 shows the blank ready to be shaped. Figs. 13 and let show top and bottom perspective views, respectively, of the coin-case, substantially as described. Fig. 15 shows detached perspective views of the parts of the dies. Fi 16 is a detail elevation showing the guards for the feed-rolls. Fig. 17 is a detail elevation showing the extractor-actuating mechanism.

My invention relates to the manufacture of folding coin-cases, comprising two semicylinders hinged together, adapted to be closed to form a cylinder of suitable diameter and length to hold a definite number of coins.

Heretofore somewhat similar coin-cases have been made, and they'have been manufactured from a single thickness of cardboard or paper, and ordinarily have been manufactured by hand.

I have found that cases made of a single thickness of paper have many disadvantages. If made from light paper, they will not hold their shape, and if made from heavier paper they will crack in shaping and use, and there is necessarily a waste of material, while by Serial No. 442,092. (No model.)

making them of a single sheet of paper doubled and pasted,with the edges reinforced by a fold of the doubled blank, I obtain the necessary stiffness, with the desired strength at the edges, where it is required, and a minimum of material. To .construct such a case, I em ploy the following process carried out by the herein-described machine.

A is a suitable frame for the operating parts of my machine. Centrally of the frame is the shaft B, upon which is spirally wound a paper strip G.

D is a guide, over which the strip passes, and E is a pasting-roller dipped in a suitable paste-pan F.

F is an idler-roll resting upon the top of a strip to hold it in contact with the pastingroll.

The pasting-roll is of suitable shape to paste the strip through its central portion, preferably separated centrally to leave a section F (shown in Fig. 8) free from paste. The strip next passes over the roll G and beneath a sprin g-act uated creasing-wheel G. The strip passes forward from the roll G beneath the curved guide H, which is of a width corresponding substantially to the distance between the creases made by the wheels G.

H is a folder consisting of a bed-plate and marginal flanges H forming tapering guideways from one end of the plate to the other. The guide H, together with these flanges, folds in the edges of the paper strip upon the pasted portion on the line of the grooves formed by the creasing-wheel G, as shown in Fig. 1, and when thus folded the strip passes between compression-rolls I, which press the unturned edges to the strip and which are provided with circumferential creasing-flanges I, which form marginal grooves or creases in the folded edges of the strip. The strip next passes beneath an idler-roll J of a width equal to the distance between the creases, this roll being slightly in advance of the folder J, which is of substantially the same construction as the folder H heretofore described, having flanges forming gradually-narrowing guide-grooves for turning in the edges of the strip.

The operation thus far described is shown more particularly in Figs. 1, 2, 8, 9, 10, and 11. Fig. 8 shows the strip its full width. Fig. 9

shows it with the edges turned in and pasted upon the body with dotted lines at K, showing the path of the creasing-rolls I, while Fig. shows the strip as folded upon itself with the reinforcing edges, Fig. 11 showing an end elevation of the strip at this stage of the operation.

K is an ink-feeding roller for the liningroll K which is provided with a suitable flange for marking lines upon the surface of the strip.

L is a printing-press of any known or usual construction, adapted to print from the under side against the platen M, which is above the strip and supported by an arched frame M. This printing mechanism preferably comprises the form T secured to the rock-arm T upon the rook-shaft T together with the inking-roll T and the inking-plate T The strip next passes over the roller N at the front end of the frame, and from thence downward in an inclined direction between the feed-rollers O, which are intermittently-driven rollers, and draw the strip through the machine for the entire operation. As the paper is drawn through the machine by means of the driven rollers 0 it imparts motion to the roller I, upon the shaft of which, at one side of the machine, is formed the grooved wheel 0, and motion is transmitted from this grooved wheel to the grooved wheel 0 upon the shaft of the pasting-roller E bymeans of a belt or rope P. Motion is intermittently transmitted to the feed-rollers 0 from the drive-shaft Q, having a suitable drive-pulley Q and provided at one end with the crank Q From this crank extends a connecting-rod Q connected atits outer end with a crank R, j ournaled upon the shaft R. The crank R carries a pawl R which carries with it the ratchet-wheel R journaled upon the shaft R and secured to a drive-gear S, which meshes with a pinion S upon the shaft of one of the feed-rollers O, the shaft of the other roller being provided with an intermeshing pinion 8*. It is evident from this construction that at each revolution of the shaft Q and crank Q during half of the revolution a rotary motion will be imparted to the feed-rolls, while during the other half they will remain stationary, the pawl moving backward upon the ratchetwheel. In this manner I get an intermittent feed to my strip, the length of the feed being equal to the length of the strip required to make a single coin-case. During the interval that the strip is at rest the printing-machine is actuated by means of a crank T upon the shaft Q through the medium of a connectingrod T and the bell-crank lever T connected with the actuating-arm of the printing-niachinethat is, when the actuating-arm is rocked by the bell-crank lever T the form T is pressed up against the strip, and in the return movement the inking-rolls are drawn over the form as in the usual construction of printing-presses. During the same interval a shaping-die U is actuated to trim the blank into the desired shape preparatory to its entering the forming-dies. The object of trimming it is to enable me to form a hinge and the fastening device for the ends to the best advantage, and to this end the shaping-die is provided with cutting portions adapted to out off the corners a b, as shown in Fig. 12, and to cut a V-shaped notch c at substantially the middle of the blank, or at the point where the hinge is to be formed between the two sections. This shaping-die U is actuated by the cam U 011 the shaft Q, which actuates the bell-crank lever U pivoted upon the transverse shaft U one end of this lever resting upon the top of the shaping-die. The die is provided at each side with an apertured lug d, through which passes a rod e, upon which are sleeved the springs f. Supported by one which the cuttings from the die strike and p are prevented from falling onto the rollers 0.

s the die is moved downward by the lever U the springs are compressed, and when the cam is turned to the upper position the springs are free to act and lift the die for another operation. The lever U also actuates the cutting-off mechanism, which mechanism consists of a stationary blade 9 beneath the strip just in advance of the feed-rollers O and the movable blade g just above the strip and secured to the front end of a lever 9 The actuating-arm of the bell-crank U is provided with a pin it, which engages in an aperture in the lever 9 so that when the lever U is actuated it will carry down with it the lever g and cause the knife g to pass the knife 9 and cut off the strip in advance of the feedroll, the section which is out off forming a blank, as shown in dotted lines in Figs. 10 and 11, and shaped as shown in Fig. 12. I next shape this blank into a coin-case, which case is shown in Figs. 13 and 14 and consists of thectwo semicylindrical sections i,the hinge j, the securing-flap 70 at one side, and the inwardlyextending flanges Z at each end of each section 2', this flange forming the means of preventing the longitudinal displacement of the coin from the case I Will next describe the construction of the dies, which consist of two parts.

1 is a cameo die, and 2.the intaglio die.

3 is the guide for the die 1, and 4 are guiderods on the under side of the die 2, passing through guide-slots in the frame 5, the springs 6 being sleeved upon these rods to bear against the under side of the die 2.

The die 1 is actuated from the shaft Q by means of a crank 7, formed thereon, and the connecting-rod 8. The die 1 is provided with two downward-projecting semicylindrical bosses 9, separated by a groove 10, as shown in Fig. 4.

11 is a creasing-blade secured to the end of the spring-backed arms 11, which slidingly engage in guide-grooves in the die 1, entering through the groove 10.

Fig. 1.)

edge of the creasing-blade 11.

The die 2 is provided with semicircular grooves 13, corresponding to the bosses 9, and a central raised portion 14', corresponding in width substantially to the width of the groove 10. This raised portion 14 is provided with a central notch or groove 15 in line with the The die 2 is provided with longitudinal slots 16, in which the extractor plates 17 slidingly engage. These plates are preferably connected together and have an extension 18 connecting with the yoke-shaped frame 19, which at its upper end is connected to the lever 20. (See This lever has a finger 22 extending upward therefrom.

23 is a roller-pin secured on the die 1. In the downward movement of this die this pin strikes upon the shoulder 2% at the top of the frame 19 and pushes down the extractorplates below the bottom of the semicircular grooves in the die 2. I11 moving down the frame 19 it also moves downward the lever 20 across the path of the roller-pin 23, so that in the upward movement of the die the rollerpin will strike the under side of the lever 20 and raise it and the extractor-plates, causing the extractor-plates to be lifted to the position shown in Fig. 6, with their upper edge flush (or nearly so) with the upper face of the lower die, thereby pushing out the coincase formed in the die in the downward movement thereof. \Vhen the roller-pin 23 passes the end of the lever 20, it will continue its movement upward parallel with the face of the finger 22, retaining the extractor-plate in its upper position until it again moves downward and strikes the shoulder 24.

At theright hand of Fig. 15 is shown detached the ironing-plate 25 for turning over and ironing the inwardly-extending flange Z of the coin-case. These ironing-plates are secured on the frame at each side of the lower die by means of adjusting-screws 26. Gasjets 27 throw a flame against their outer surfaces, keeping them at all times at a high temperature. The gas-jets will also maintain the dies in a highly-heated condition. These plates have a short distance below their upper end the flange 28, correspondingin shape to the shape of the lower die, and below these flanges is formed an ironing-surface 29.

I will now proceed to describe the operation of the forming mechanism at the front end of the machine.

The parts being in position, as shown in Fig. 4:, the rotation of the shaft Q will turn the crank 7 and cause the die 1 'to approach the die 2. The creasing-blade 11 will first strike in the groove 15, the parts being then in position, as shown in Fig. 5. Simultaneously with the striking of this creasing-plate upon the lower die the cam U will actuate the lever U and through the connections described will cause the upper knife G to descend past the stationary knife and sever the blank from the strip, cutting it, as shown by the dotted lines 29, Fig. 12. The upper die will continue to descend, lowering the extractor-plates, as previously described, and causing the semicircular bosses 9 to enter the semicircular groove 13, shaping the blank into two semicircular sections separated by the raised portion 14.. The pressure of the creasing-blade 11 in the groove 15 will at the same time form a longitudinal groove which serves as a hinge between the two semicylindrical sections. The upper die continuing its downward movement will force the lower die downward, compressing the springs 6. In this further downward movement the ends of the blank which project over. the flanges 28 of the ironing-plate 25, as shown in Fig. 3., will be forced between the sides of the upper die and the ironing-face 29 of the ironingplate, as shown in Fig. .7, and during both the upward and downward movement of the two dies beyond the initial position this flange will be ironed against these plates, which, as before described, are highly heated. The result of this ironing of the flanges is to dry up the paste and iron them into a stiff flange which will stand considerable strain and pre vent endwise disengagement of the coin even with rough handling. As the upper die withdraws the lower die is caused to follow it by the expansion of the springs 6 until it has reached its initial position, then the upper die is lifted away from it; the extractors are moved up, and the coin-case thrown out ready for another operation.

In order to enable me to overlap the meeting ends of the sectionsof the coin-case, I form the end 30 slightly thelonger. In order to give this longer end the necessary curvature, I preferably form the upper die with a curved side recess 31 and provide a roller 32, secured to a lever 33 and actuated by a spring 34 toward the dies, all so arranged that as the dies descend the spring 34 will press the roller 32 against the end 30 of the blank and roll this end into the recess 31, both in its upward and downward movement, so that the flap will be substantially of the same curvature as the two sections of the coin-case and the ends will more readily go together in using. The gas-jets which heat the ironing-plates also highly heat the lower die, the result being that while pressed in the heated dies the paste will be rapidly dried and the case will be stiffer and will better retain its shape.

What I claim as my invention is 1. In a machine for manufacturing coincases from a roll of paper, the combination of means for feeding it in a strip, a pasting-roll for pasting one side of the strip, mechanism for doubling the strip, a pressure-roll for pressing the doubled blank together, mechanism for folding in the edges of the doubled blank, a cutter, dies for forming the case and actuating mechanism, substantially as described.
